Abstract

The utility model relates to an adjustable pot stand for household gas stoves, which is composed of a pot frame and an adjustable cylinder. The inner part of the adjustable cylinder 2 is provided with a plurality of groups of bosses with different heights, and the distance of each group of the bosses with the same height equals the distance of each pot ear on a pot frame. The pot frame can be arranged on each group of the bosses in the adjustable cylinder by the pot ear, the height of the pot frame can be adjusted in time according to the using air supply and the selecting firepower at the time of cooking, and the effect of efficient energy saving is realized. The utility model has the advantages of simple and reasonable structure and convenient adjustment, and the content of carbon monoxide can be reduced.

Description

The household gas range adjustable cauldron rack

The utility model relates to a kind of pot of frame, particularly a kind of household gas range adjustable cauldron rack.

At present domestic several big burner manufacturer generally only pays attention to the calorific value research of different gas kinds, under the situation of not placing cooker and rated heat input, rated heat load, the assurance combustion gas is fully burnt, and ignored different air feed conditions, when the different cookings required, fuel gas buring was different with heat transfer situation.Because: one, liquefied petroleum gas calorific value height reaches 25000～28000 kilocalories/M approximately ³, the required primary air that burns is more, is about 0.7, and burning velocity is slow, and the result is that flame is thin and long, and the flame envelope district is far away from flame hole, and should suitably heighten the pot frame this moment; Two, opposite, the calorific value of artificial coal gas is low, has only 1500～9000 kilocalories/M ³, the required primary air that burns is less, is about 0.3, and burning velocity is fast, and the result is that flame is thick and short, and the flame envelope district is near from flame hole, and should suitably turn down the pot frame this moment; Three, every characteristic index of natural gas is between said two devices, and its length of flame is also between said two devices.In addition, the size of required firepower was taken all factors into consideration when also used on the border factually, adjusted a pot frame height in good time, to reach effect such as energy-conservation.If keep pot frame height constant, must cause under most of situation, burning and heat-transfer effect can not reach original designing requirement, and the result produces a large amount of harmful CO, and causes integrated heat efficiency to descend.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of selected firepower size can be according to the source of the gas that uses and the cooking time is provided and in time adjusts a pot frame height, to reach the household gas range adjustable cauldron rack of energy-efficient effect.

The purpose of this utility model can reach by following measure: the utility model comprises a pot frame, it is characterized in that: also have the tube of adjustment, adjust the boss that is provided with many group differing heights in the tube, the distance of each handle on the distance between every group of level boss and the pot frame is corresponding, and the pot frame can be put in by handle and adjust respectively organizing on the boss in the tube.

Fig. 1 is for adjusting the structure chart of tube;

Fig. 2 adjusts the A of tube to expanded view;

Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment);

With reference to Fig. 1～Fig. 3, the utility model is made up of pot frame 1, adjustment tube 2, adjust the boss 3 that is provided with many group differing heights in the tube 2, the distance of each handle on the distance between the boss 3 of every group of equal altitudes and the pot frame 1 is identical, pot frame 1 can be put on the boss of adjusting in the tube 2 of respectively organizing differing heights 3 by handle 4, thereby adjusts the height of pot frame 1, and the bottom of a pan is contacted with the flame envelope of flame, reduce the influence of the bottom of a pan to greatest extent, guarantee the completing combustion of combustion gas fuel gas buring; Simultaneously, the flame envelope district temperature of chafing dish is the highest, and show with measured result repeatedly according to hot transfer theory: when the bottom of a pan contacted with flame envelope, heat transfer efficiency was the highest.

The utility model has following advantage compared to existing technology;

1, selected firepower size in the time of can be according to the source of the gas that uses and the cooking and in time adjust pot The frame height, thus reach energy-efficient effect, and can reduce the content of CO.

2, simple and reasonable, easy to adjust, practical reliable, can be in the penetration and promotion of vast family.

Claims

1, a kind of household gas range adjustable cauldron rack comprises pot frame 1, it is characterized in that; Also have to adjust tube 2, adjust the boss 3 that are provided with many group differing heights in the tube 2, the distance of each handle 4 is corresponding on the distance between every group of level boss 3 and the pot frame 1, and pot frame 1 can be put in by handle 4 and adjust respectively organizing on the boss 3 in the tube 2.
